How accurate is the AI Content Detector?

The detector identifies common AI writing patterns with reasonable accuracy. No detector is perfect. Use results as guidance, not definitive proof. Accuracy varies based on how much the AI text has been edited.

Is the AI detector free?

Yes. You can check up to 3,000 words per request for free with your Miniloop account. There are no daily limits on how many checks you can run.

What AI models can it detect?

The detector identifies patterns from major AI models including ChatGPT (GPT-3.5, GPT-4), Claude, Gemini, Llama, and others. All large language models share similar statistical patterns.

Can it detect AI-assisted writing?

AI-assisted writing (human writing improved by AI) is harder to detect than pure AI output. The more human editing involved, the lower the detection score will typically be.

Why does human writing sometimes score high?

Some human writing styles, especially formal academic or technical writing, can trigger false positives. Highly structured, well-organized writing may resemble AI patterns. Use results as one data point, not proof.

Can students use this to check their work?

Yes. Students can check their own writing to ensure it doesn't accidentally trigger AI detectors, or to verify that their AI-assisted drafts have been sufficiently personalized.

What does the probability score mean?

The score indicates how likely the text is AI-generated based on detected patterns. 0-30% suggests human writing, 30-70% is uncertain, and 70-100% suggests AI generation.

Does it work for non-English text?

The detector works best with English text. It can analyze other languages but may be less accurate at detecting AI patterns specific to those languages.

Is this better than GPTZero?

Both tools detect AI content effectively. GPTZero offers higher free word limits and batch processing. This tool provides detailed pattern explanations and is completely free for individual checks. Try both for important decisions.

Can AI text be made undetectable?

AI text can be rewritten to reduce detection scores. Significant human editing, adding personal examples, and varying writing style all help. See our AI Humanizer tool for automated assistance.

Does copying from AI detectors count as proof?

No. AI detector results are probabilistic estimates, not proof of AI use. They should be used as a flag for further review, not as definitive evidence in academic or professional contexts.

What is the best free AI detector?

This tool offers free detection with detailed pattern analysis for up to 3,000 words. GPTZero offers 5,000 words free. Both are solid choices for free AI detection. For the most important decisions, cross-check with multiple tools.

How do I check if my essay is AI?

Paste your essay into the input area and click Check for AI. The detector will analyze the text and provide a probability score with specific patterns it identified. Review the results before submitting.

Can teachers tell if I used ChatGPT?

Teachers may use AI detectors like this one to flag potential AI usage. However, detection is not proof. If you use AI as a writing aid, make sure to substantially edit and personalize the content, and follow your institution's policies on AI use.

AI Content Detector

Check if text was written by AI or a human. Analyze any content and get a detailed probability score with specific patterns detected. Free and accurate.

How to detect AI-generated content

What is the AI Content Detector?

The AI Content Detector analyzes text and determines the probability that it was written by an AI like ChatGPT, Claude, or other language models. It examines writing patterns, sentence structures, and stylistic markers to provide an accurate assessment.

The detector returns a percentage score along with specific reasons for its verdict. This helps you understand not just whether text is likely AI-generated, but why it appears that way.

More than a simple score

Most AI detectors give you a number and leave you guessing. This tool shows exactly which patterns triggered the detection: repetitive sentence structures, overused transitions, unnaturally consistent paragraph lengths, and other specific markers.

Understanding why text was flagged helps you make better decisions. For educators, it opens conversations about writing style. For content creators, it shows what to edit. For anyone checking their own work, it reveals exactly what needs to change.

How to check if text is AI-generated

Detecting AI content takes just a few steps:

1
Paste your text
Enter the content you want to analyze. You can paste up to 3,000 words. Use the sample buttons to test with example texts.
2
Click Check for AI
The detector analyzes the text for AI patterns including statistical signatures, stylistic markers, and consistency issues.
3
Review the results
See the AI probability percentage (0-30% likely human, 30-70% uncertain, 70-100% likely AI) along with specific patterns detected.
4
Take action
Use the detailed feedback to make decisions: approve the content, request revisions, or edit to address the flagged patterns.

How AI detection works

AI detectors look for patterns that distinguish machine-generated text from human writing:

Statistical patterns

AI models generate text based on probability distributions. This creates subtle statistical signatures in word choice and sentence structure that differ from human writing patterns.

Stylistic markers

AI tends to use certain phrases, transitions, and sentence constructions more frequently than humans. Words like 'Furthermore,' 'Moreover,' and 'It is important to note' are common tells.

Consistency analysis

Human writing naturally varies in tone, sentence length, and complexity. AI output is often unnaturally consistent and polished throughout.

Perplexity scoring

AI-generated text typically has lower perplexity (more predictable word choices) than human writing, which tends to include unexpected phrasing.

AI Detector vs GPTZero vs Originality.ai

Here is how this tool compares to other AI detectors:

Feature	Miniloop (Free)	GPTZero	Originality.ai
Price	Free	Free / $10 mo	$14.95/mo
Word limit (free)	3,000	5,000	None (paid)
Pattern explanations	Yes	Limited	Yes
Batch checking	No	Yes (paid)	Yes
Browser extension	No	Yes	Yes

Tips for using AI detection effectively

Understand what the scores mean. 0-30% suggests human writing with natural variation. 30-70% is uncertain territory, often AI-assisted writing that was edited. 70-100% indicates strong AI patterns and high confidence of machine generation.

No AI detector is 100% accurate. False positives occur with highly structured human writing like academic papers and technical documents. False negatives occur when AI text is heavily edited. Use detection as one data point, not definitive proof.

For important decisions, cross-check with multiple tools. Different detectors use different methods and may catch different patterns. Combine automated detection with human judgment about context and writing style.

Why use an AI detector?

Maintain content authenticity

Readers and audiences value authentic human perspectives. Knowing whether content is AI-generated helps you maintain trust and credibility in your publications, whether you're running a blog, news site, or academic journal.

Support academic integrity

Educational institutions use AI detectors to identify potential academic dishonesty. While not definitive proof, detection results can flag submissions for closer review and open conversations about appropriate AI use.

Three-step workflow showing AI draft, editing, and checking before publishing

Verify your own content

If you use AI as a writing assistant, check your final content before publishing. Ensure your edits and personal touches have made the text sound naturally human and won't trigger detection tools.

Who can benefit from AI Content Detector?

Built for anyone who needs to verify the authenticity of written content.

Educators

Check student submissions for AI-generated content. Identify which parts may need further review or discussion about academic integrity.

Editors & Publishers

Screen freelance submissions and guest posts before publishing. Ensure content meets authenticity standards for your publication.

Hiring Managers
